Kyle Prater's on-again, off-again relationship with USC is back on -- for good. And he's moving to California to prove it.

After twice committing to play at USC for Pete Carroll over the past five months, the Proviso West wide receiver will do so again as soon as he talks to Carroll's replacement, Lane Kiffin, according to his mother, Sonya Prater.

Kiffin was recruiting Prater for Tennessee before agreeing to be Carroll's replacement on Tuesday -- a day after Carroll officially took over as head coach of the Seattle Seahawks.

"He's leaving this weekend and will start classes Tuesday," Sonya Prater said. "Coach Carroll is a great guy and we believe Coach Kiffin is a great guy as well. We have a great relationship with him. We believe he can do the same thing he did there a few years ago (as a USC assistant from 2001-06.)

"Once he (Prater) found out about Kiffin, that was a great thing. He needed that. It was a blow that Coach Carroll left."

Ranked the top receiver in the country and the No. 2 prospect overall by Rivals.com, the 6-foot-5 Prater originally committed to USC in September at a press conference at Proviso West. Not long after, he decided to keep his recruitment open and took official visits to Notre Dame and Illinois.

In December, Prater re-affirmed his commitment to USC before graduating early from Proviso West to enroll at USC so he could participate in spring practices. It is common for recruits to change their minds after making oral commitments, which are not binding and do not become official until national signing day on Feb. 3.

"The coach plays a part, but it wasn't first and foremost," Sonya Prater said. "Coach Carroll called us (after leaving USC) and told Kyle to go to USC because it is a great institution."
